Eternal Century V2 - Minecraft Game Server Customization

By Oska Ng on Aug 1, 2021


This involves building plugins in Java/Kotlin to modify Minecraft’s default behavior. It includes numerous homemade features such as an item system to enhance both PvE and PvP experiences, a GUI system for buying and selling items from NPCs, and an NPC system supporting various functions like storage, item repairing, titles, auctions, and quests. Additionally, it features simple daily and weekly quests, as well as automatic boss spawning and custom events based on specific times in UTC+8.

This project underwent production testing and successfully went live for a duration of 1-2 months, supporting approximately 20-50 concurrent online users while maintaining stability. The decision to discontinue was prompted by the extensive time required for teardown, and the impracticality of maintaining this type of server when time constraints are a limiting factor.
